the question is, how can you use or use the NCG and Dixmier traces to erase the UV divergences (short distance)

i have read some of Connes work but i do not fully understand it for example he uses de notation

\int T |D|^{n} = Res (s=1) Tr { T|D|^{-s}}

or something similar and do not use the metric g_ab
